Jack Z7-181000
– Adaptive Hump-Jumping Heavy Duty Sewing Machine.
The JACK Z7 is a heavy-duty, triple-transport industrial lockstitch machine designed for sewing thick and challenging materials like leather, automotive upholstery, and multi-layer fabrics. Equipped with an intelligent thickness-sensing system, a powerful 850 W motor, and automatic features such as thread trimming, back-tacking, and programmable controls, it delivers stable, consistent stitching even across sudden thickness changes. With its large hook, pneumatic foot lifter, and user-friendly touch-screen interface, the Z7 combines strength, precision, and ease of operation—making it ideal for demanding professional applications.
Triple Transport
This machine features synchronized movement of the feed dog, needle, and walking feet, ensuring powerful and consistent material feeding. It is specially designed for heavy-duty applications such as automotive components (steering wheels, seats), sofas, bags, mattresses, and other thick or multi-layer materials.
Artificial Intelligence
An integrated AI chip instantly detects changes in material thickness and resistance, sending real-time data to the motor. This allows the machine to automatically increase needle penetration force and motor torque, ensuring smooth, stable stitching and improved feeding efficiency even on demanding materials.
Thickness Sensor
The built-in thickness sensor detects variations in fabric height and automatically activates the second alternating sewing foot along with the additional thread-tensioning system. This ensures optimal feeding, consistent stitch quality, and smooth performance throughout the entire seam.
Double Alternating Sewing Feet
Equipped with two adjustable knobs, this system allows the operator to set and switch between two alternating sewing feet. The feet can be activated automatically—based on material thickness or overlap detected—or manually, ensuring precise feeding and consistent stitch quality on varied fabrics.
Additional Thread Tension Device
A secondary thread-tension system can be activated either automatically—based on detected fabric thickness or overlaps—or manually. This ensures optimal stitch formation and consistent seam quality across a wide range of materials.
Double Stitch Length
For corners and other detailed seams that require shorter stitches, the Jack Z7 automatically adjusts the stitch length with the press of a button—eliminating the need to manually adjust the knob. This ensures precision and efficiency in complex sewing tasks.
Touch Screen Panel
The intuitive touch screen panel uses voice guidance and clear icons to quickly and easily activate or deactivate functions such as bartack, presser foot lifter, thread trimmer, and more. Long-pressing a button provides access to the function settings interface for advanced configuration and customization.
Electronic Handwheel
The integrated digital handwheel allows precise micrometric adjustments with simple rotation. A single click enables half-stitch operation, giving the operator full control for detailed sewing and accurate stitch placement.
Function Keys
Conveniently located on the machine head, the function keys allow quick access to frequently used operations. One key can be fully customized via the touch screen panel to perform a desired function, improving workflow and efficiency.
850W Powerful Motor
Equipped with the most powerful motor in its category, the Jack A2B-C delivers 13% more power compared to competing triple-feed lockstitch machines. This ensures superior performance, consistent stitching, and reliable operation even on heavy or multilayer materials.
Pneumatic Presser Foot Lifter
Equipped with a double-alternating pneumatic presser foot lifter, this system provides smooth, consistent lifting and lowering of the presser foot. It enhances operator efficiency and precision, especially when handling thick or multi-layer materials.
XXL Hook
The 32mm XXL hook accommodates thick threads and continuous seams with ease, offering 73% more capacity compared to the standard 2X hook type. This ensures smooth stitching and reduces thread jams, even in heavy-duty applications.
